Claus Ibsen commented on CAMEL-5567:
------------------------------------
Alan, do you have a real-life use-case for this need?
And frankly you can do this in Java code, and use a method call expression to
setup in the XML DSL.
> Add Multiple correlation Ids to the Aggregator component

> Key: CAMEL-5567
> URL: https://issues.apache.org/jira/browse/CAMEL-5567
> Project: Camel
> Issue Type: Improvement
> Reporter: Alan Foster
>
> Currently the aggregator component allows users to specifiy one expression
> that they would like to use for aggregation
> It would be nice to add many different correlation expressions for all of the
> different payload contents that an aggregator can receive
> For instance it may look like
> {code}
> <camelContext xmlns="http://camel.apache.org/schema/spring";>
> <route>
> <from uri="direct:start"/>
>
> <aggregate strategyRef="aggregatorStrategy" completionTimeout="3000">
> <correlationExpression>
> <!-- If this xpath returns nothing try the next expression
> etc -->
> <xpath>/AcmeServiceResponse/CorrelationId/text()</xpath>
> <xpath>/FooResponse/Id/text()</xpath>
> <xpath>/CorrelationKey/text()</xpath>
> </correlationExpression>
> <to uri="mock:aggregated"/>
> </aggregate>
> </route>
> </camelContext>
> {code}
> I wonder what your thoughts are on this suggestion? If it seems like a good
> idea I can start to make a patch for it
